What is the max voltage you are looking for?
What kind of vehicle?

The Xiaomi M365 scooter controller is cheap and abundant: https://www.ebay.com/itm/284916660444
Fairly capable, (field oriented control, regen) and you can flash open source firmware if desired:

You can swap in a higher 100v capacitor, and change the voltage divider resistors for higher voltage operation.
just to name a few,

Also, the Flipsky 75100 is an option.
